Oil on concrete . . . Ray 09-22-2007

I recently moved into a house with an enclosed garage, and the floor had a 3
x 6 foot patch of motor oil which apparently leaked onto the floor years
ago. It is not totally hard, but more like the consistency of stiff dough.
It will scrape up if I keep at it, but it would take many hours of
back-breaking work to do this.

Any ideas how to get it up faster would be welcome.

Also how to get out the oil stain insofar as possible.

Any solvent based cleaner will let the oil go deeper into the
concrete. If you have a power washer or high pressure on your
garden hose, soak the area with Simple Green, engine degreaser
(from an auto parts), or one of the citrus based cleaners. I'd
let it soak overnight with plastic or a bucket over it to keep it
from evaporating. Go after it the next day with water, scrub
brush, stiff broom, putty knife, and more of the cleaner. This
may be a good quitting point. If you want to try to get more of
it, place dry Portland cement on it. Put it on heavy. It will
absorb the oils. This is not a fast process and may need several
repetitions.

Thanks -- I'll give that a try. I don't want perfection, just hope to get
that layer of gunk off the floor.

First, cover the spot with kitty-litter. Let the litter sit for as long as
necessary (stirring every day or so), until it soaks up as much of the oil
as it can. Plan on several days.

This reduces your problem by a magnitude or so.

My cats prefer the "clumping" kind of litter.
